Peradur

Peradur (died 878) was one of the Kings of Cornwall during the 9th century. Infamous for having two wives (with Iseult serving as his "shadow queen"), he was killed by the Viking raider Skorpa of the White Horse during the Sack of Cornwallum in 878.

Biography
Peradur was born in Cornwall to a pagan family; while he became a Christian, he could not let go of his old pagan ways. He became one of the many kings of Cornwall, and he married two women, with the gwrach Iseult serving as his "shadow queen". In 878, he sent his servant Brother Asser to recruit Uhtred of Bebbanburg's "Danish" brigands to help him retake a fort from Skorpa of the White Horse and his Vikings, offering him 400 silver pieces. The brigands believed that they would fight Britons, but, when they discovered that they were fighting real Danes, they decided to betray Peradur. They helped the Vikings kill all of Peradur's men, and Peradur forced Skorpa to promise that he would spare him. Peradur then revealed that his treasure was hidden in a hole under his throne, and Skorpa broke his word by stabbing Peradur in the heart.
